High-voltage level-shifter architectures that provide galvanic coupling between low/high-voltage domains while simultaneously enabling high speed operation, low static current consumption and high reliability under a myriad of environmental circumstances including electromagnetic interference as well as process, voltage and temperature variations.

High-voltage level-shifter circuitry

An analog/digital converter (ADC) includes an analog stage with at least one first sigma-delta modulator and includes a digital stage with at least one second sigma-delta modulator. The analog stage is configured for outputting a digital signal to the digital stage that is indicative of a noise contribution of the at least one first sigma-delta modulator. The analog stage and the digital stage may be arranged in a multi-stage noise shaping architecture (MASH) architecture.

Hybrid digital/analog noise shaping in the sigma-delta conversion

Representative implementations of devices and techniques provide configurable multi-channel analog-to-digital conversion. In a multi-channel analog-to-digital converter (ADC), one or more ADC stages may be operatively coupled to a different ADC in each of various operating modes.

Configurable hardware-sharing multi-channel ADC

This disclosure relates to a Phase-Locked Loop (PLL) device and a method for providing a stable free-running voltage signal to a voltage controlled oscillator.

Active free-running frequency circuit for phase-locked loop applications

An apparatus described herein is an LC tank circuit that may include a capacitance, a first inductance, and a second inductance. The first inductance and the second inductance may each be center tapped coils.
